Description

Looking at the source (v2_5_54_0-32-g5aa4ccc) I see several accesses to the members of lu_dirpage and lu_dirent that do not use leXX_to_cpu(). Here are a few:

d lustre/mdc/mdc_request.c     mdc_read_entry               1676 if (dp->ldp_hash_end == MDS_DIR_END_OFF) {
e lustre/mdc/mdc_request.c     mdc_read_entry               1681 op_data->op_hash_offset = dp->ldp_hash_end;
f lustre/mdc/mdc_request.c     mdc_read_entry               1762 if (dp->ldp_hash_end < op_data->op_hash_offset)

9 lustre/mdc/mdc_request.c           mdc_read_entry               1667 if (ent->lde_hash > op_data->op_hash_offset)
a lustre/mdc/mdc_request.c           mdc_read_entry               1767 if (ent->lde_hash >= op_data->op_hash_offset)

I didn't try to find all of them.
